What to Pack for Ha Long Bay

Packing for Ha Long Bay is simpler than most travellers expect — but getting it wrong can significantly affect your comfort. The combination of heat, water, cave walking, and boat living in a single trip requires a specific set of items. This guide covers exactly what to bring, what to leave behind, and how packing differs for day trips versus overnight stays.

Ha Long Bay Cruise Essential Packing List

Sun Protection

High-SPF sunscreen — Ha Long Bay’s karst landscape reflects sunlight intensely, and the open water environment means there is little natural shade for extended periods on deck. Apply before boarding and reapply after kayaking or swimming. SPF 50 is the minimum recommended.

Hat — a wide-brimmed hat is more practical than a cap for protecting your face, neck, and ears during time on the open deck. Bring a chin strap if you are prone to losing hats in the wind.

Sunglasses — essential for the water glare, particularly on clear days in the dry season when light off the bay is intense.

Footwear

Closed-toe shoes or trainers — the cave visit is non-negotiable in this regard. Ha Long Bay’s caves involve walking on uneven, sometimes slippery limestone surfaces. Sandals are manageable but closed-toe shoes provide significantly better grip and protection. Lightweight trainers or walking shoes are ideal.

Sandals or flip-flops — bring a second pair for the boat and beach time. Dry faster than trainers and are more comfortable in the cabin and on deck.

Swimwear and Water Items

Swimwear — one or two sets. Quick-dry fabric is better than cotton, which takes hours to dry in humid conditions.

Quick-dry towel — most cruises provide towels in overnight cabins, but day cruise operators rarely do. A compact microfibre travel towel takes minimal bag space.

Dry bag or waterproof phone case — the most commonly forgotten practical item on a Ha Long Bay cruise. During kayaking, your phone and valuables go in the kayak with you and get splashed. A dry bag the size of your phone (or slightly larger to include a wallet and keys) is inexpensive and essential. Available in Hanoi’s Old Quarter at most outdoor gear shops.

Rashguard or UV shirt (optional) — useful for extended kayaking or snorkelling sessions, particularly in summer when UV intensity is highest.

Clothing

Light, breathable clothes — Ha Long Bay is humid. Linen, cotton, or moisture-wicking synthetic fabrics are more comfortable than heavy materials. Pack clothes you can layer — mornings on the boat can be significantly cooler than afternoons.

Light jacket or fleece — essential for October to April visitors. Evenings on the open water can feel considerably cooler than Hanoi, especially in December and January. A light down jacket or fleece is sufficient; a heavy coat is not necessary except in the coldest winter months.

Change of clothes after swimming — bring at least one complete change to put on after your swimming stop on day cruises, or two to three changes for overnight stays.

Smart-casual outfit (optional, overnight only) — some 5-star overnight cruises have a slightly more elevated dinner atmosphere. A clean shirt or simple dress is sufficient — Ha Long Bay is not a formal occasion.

Toiletries and Health

Personal medications — particularly motion sickness tablets if you are sensitive to boat movement. Ha Long Bay is sheltered and generally calm, but smaller or older vessels can rock more noticeably. Take medication before boarding if you are concerned.

Insect repellent — mosquitoes are present in sheltered coves and around island vegetation, particularly at dusk. A DEET-based repellent is effective; non-DEET alternatives work well in moderate conditions.

Hand sanitiser — useful at cave stops and before meals.

Basic first aid — plasters, antiseptic wipes, and painkillers. For anything beyond minor cuts and headaches, the boat’s crew will assist.

Personal toiletries — overnight cruises on 5-star vessels provide basic toiletries (shampoo, soap, toothbrush). Mid-range and budget overnight boats may provide very little. Bring your own as a safe default. Day cruises provide nothing — bring everything you need.

Electronics and Photography

Camera or phone — Ha Long Bay is one of the most photogenic places in Southeast Asia. Bring what you need, but protect it. The dry bag mentioned above is essential for kayaking.

Portable charger / power bank — overnight cabin boats have cabin power sockets, but shared deck areas may not have accessible charging. A power bank ensures you stay charged through a full day of photography.

Waterproof camera (optional) — for underwater shots at the swimming stop or kayak-level photography of the karst formations. Action cameras with waterproof housing are popular on Ha Long Bay.

Documents and Money

Booking confirmation — save it to your phone and have a screenshot accessible offline. Some boarding docks have limited mobile signal.

Passport — Ha Long Bay national park entry requires identification. Keep it secure in your cabin during water activities.

Cash in Vietnamese dong — alcoholic drinks, optional activities, and gratuities are typically cash only on board. ATMs are not available on the water. Bring sufficient cash before leaving Hanoi.

Day Cruise vs Overnight Packing: Key Differences

What NOT to Bring on a Ha Long Bay Cruise

Large suitcases — cabin storage on Ha Long Bay boats is limited, particularly on mid-range overnight vessels. A small overnight bag (30–40 litres) is the maximum practical size. Leave large luggage at your Hanoi hotel.

Valuables you cannot afford to lose — jewellery, large amounts of cash, and non-waterproof electronics should stay in Hanoi. The boat is generally safe, but there is no need to bring irreplaceable items to the water.

Single-use plastic — Ha Long Bay has a serious plastic pollution problem. Bring a reusable water bottle (refillable from the boat’s water cooler on most cruises) and avoid single-use plastic bags.

Hair dryers — some overnight cabins have hairdryers; most do not. If you need one, confirm with your operator before booking.

Ha Long Bay Cruise Packing by Season

October to April (dry season) — add a light jacket or fleece for evenings. Mornings in December to February can be genuinely cold on the water (15–18°C). Layers are more practical than a single heavy coat.

May to September (wet season) — pack a lightweight waterproof jacket or packable rain poncho. Summer thunderstorms can arrive quickly; being caught in heavy rain on the sun deck without a layer is unpleasant. Humidity is high — choose fabrics that breathe and dry quickly.
